How has our education prepared us for our career, some people have different education different work profile?

It depends on the feild, if you are for example a doctor or an engineer, education is essencial, but if we are taking about feilds like sales, marketing, hr, education is important and the most important is self develpoment and real experience.

the education dos not prepare us to any career, the work in feeld it is the right way to prepare to any career, and it is the great door to the expereans in any job field

I have a financial bechlor dgree, but I am working as graghic designer from when I was in secondary school7 years ago, I did not study the graphic design, but my feald work it is wich make my senior expearians 

It is not the education that acts as a stong foundation for our career, rather it is the experience. If a person has a different education and he is experienced in different work profile, it shows that he is challenging enough to learn and take up new responsibilities. As long you are comfortable working in a different profile, there is no problem with your educational qualification.
